. a specification.

My invention is especially uset'ul when applied to a warping-machinethat is being-used to make chain-warps of cotton, and which aresubsequently to be dyed; and it consists of the construction andcombination ot parts as hereinafter set forth.

My invention is illustrated in the accompanying drawings, in Which-Figure lis an elevation of a warping-machine that is provided with myinvention. Fig. 2 is an elevation, upon a larger scale than that of Fig.l, of certain of the important parts shown in Fig. l. Fig. 3 is apartial elevation, partly in section, at the line a a of Fig. 2, andseen when looking toward the left at that line. Fig. 4L is an elevation,seen when looking at the left-hand end, of some of the parts shown inFig. l; and Fig. 5 is an end elevation of the cut-cylinder, which issometimes used to stop the machine to which my invention is applied whena certain predeterminednumber of yards of yarn has passed therethrough.

Similar refei'encenumbers refer to similar parts in all of the views.

It is very desirable when making some kinds of warps that thewarping-machine should be stopped at intervals and leases inserted, 0rin order that cut-marks may be made to indicate the place where thecloth is to be cut apart when the warp is woven. The machine should alsobe stopped at the proper time to allow the warp-threads to be cut oftand another warp begun, and all these operations should take place whencertain predetermined lengths of yarn have passed through the machine.It is now desirable to be able Serial No. 270,342.

desirable to stop the machine at the proper times for the purpose ofinserting a lease. It is, however, frequently desirable to use awarping-machine to make what are called chain-Warps, which are to bedyed in that state, and in such a case it is often desirable to stop themachine at the end of each cut and tightly tie a string or other bandaround some of the yarn. The yarn will not in that case be fully dyedunder the band, and when the warp is put into a loom the mark so made isreadily discernible, and will serve as a guide to the weaver in cuttingoff the cloth at the proper places. When a certain. definite number ofcut-marks have been made, it is usual, when making chain-warps, to putin a lease, and the warps are usually made to contain a certain deiinitenumber of such leases, and consequently a number of cuts, which is amultiple of the number of leases in the warp. It is desirable to be ableto vary the number of yards of yarn in a cut, and the number of cutsbetween two leases, and the number ot' leases in a warp, and to stop thewarping-machines at the end of each cut and warp, whatever be the lengthof yarn in a cut, and the invention illustrated in the drawings isintended to make it possible to fulfill all of these requirements.

In the drawings, the yarn l is represented as passing through thewarping-machine and through the leasing-combs 2 to a hailing-machine,upon which it is formed into a ball, Y

I o'o lent, attached to said shaft.

the stud 6, and is firmly held in place by clamping it between the frame11 and the collar 12, by means of the nut 13. The idlerwheel 8 engageswith the cut-wheel 14. The circumference of the measuring-roll 3 and thenumbers of teeth in the wheel 5 and the pinion 7 are preferably soselected that when a yard of yarn passes over the measuring-roll,thereby rotating it by frictional contact therewith, the cut-wheel 14will be rotated through an angle equal to that occupied by one of itsteeth. The cut-wheel 14 is preferably Vwhat is known as a change-wheel,a wheel which is readily removable and replaceable by a wheel having adifferent number of teeth, and it is shown as supported upon a sleeve86, which is attached to the pinion 15, 4and as secured thereto by thenut 16. The pinion 15 is supported upon the stud 17, and engages withand turns the cut cylinder or cam 18. The cylinder 18 ispreferablyprovided with one or more pins 27, which engagewvith the teeth of thepinion 15, and which may be placed in thespace between any desired pairof consecutive teeth. This is a desirable feature, as it renders itpossible to easily adjust the position of the cut-cylinder. Thecut-cylinder 18 is provided with a notch 19, into which and toward theaxis of said cylinder the ends of the arms 2O and 2l drop when saidcylinder rotates far enough to bring said notch under said ends. Oneside of the notch 19 is nearly radial, in order that the arms 2O and 21may suddenly drop when the notch reaches them, while the other side isinclined, in order that said arms may be easily raised to their normalposition by the rotating cut-cylinder 18.

The arm 2O is iirmly attached to the rocking shaft 22, and its end iscaused to fall into the notch 19 by the weight 23 or its equiva- Thisweight 23 is attached to the shaft 22 by an arm, which holds the centerof gravity of the weight at a little distance from the shaft, thetendency of the weight to fall holding the end of the arm 2O iirmlyagainst the cut cylinder 18.

The arm carrying the weight 23 is shown as provided with acam 24, attached either directly to said arm or to said weight. This cam, whendisplacedfrom its normal-.position in consequence of the end of the arm2O dropping into notch 19,comes in contact with the finger 25 anddisplaces it, thereby stopping the warping-machine.

' The mechanism partially illustrated for stopping the machine and setin motion by the finger 25 is nearly like. the usual mechanism used forthe purpose. It is controllable by the operator of the machine at anytime, and is also put in action in the usual manner by the breaking ofany thread of the warp. Any equivalent mechanism for stopyping themachine when the cut cylinder or cam has made exactly one revolution maybe 'substituted for that illustrated whenever it is desirable to do so.The arm 21 is used in order that the gong 26 may be rung by the hammer28 whenever the end of the arm 2O drops into the notch 19. The arm 21 isloosely supported upon the shaft 22, and its end is held against thecut-cylinder 18 by the spring 29. This loose arm is used in themechanismin order that the gong 26 may be promptly struck a single blowat the moment the end of the arm 2O begins to fall into the notch 19,said arm 2O not usually falling quickly enough to properly ring saidgong by a hammer attached to it. Any equivalent quickstriking hammer maybe attached to the mechanism to ring the gong 26, when the end of t-hearm 2O begins to fall into the notch 19 instead of the arm 2l., wheneverit is desirable to do so.

The operation of the mechanism thus far described is now readily to beunderstood, and is as follows: The number of yards to be put into a cuthaving been determined, a cut-wheel 14, having the proper number ofteeth, is selected, and the idler-wheel 8 is adj usted in position inthe usual way to transfer the motion of the pinion 7 to said wheel 14,and the cut-cylinder 18 is adjusted in tho position shown in Figs. 3 and4. The machine being now set in operation will run until it is` stoppedby the breaking of some thread or by the operator of the machine oruntil the desired number of yards of yarn for one cut has passed themeasuring-roll 3. The end of the arm 20 will then drop into the notch 19again, the cam 24 at the same time stopping the machine.4 The cut-markmay now be applied or attached to the yarn and the machine may then beagain started, when it will run, if all things are in good order, untilthe end of the arm 2O again falls in to the` notch 19, when anothercut-mark may be applied or attached. It is evident that the gong 26 isstruck whenever the machine is stopped by the action of the cut-cylinder18 and its connected parts, thereby calling the attention of theoperator to the fact of the stoppage. If it be only desired to stop themachine at the end of each cut, no mechanism further than that thus fardescribed would need to be used; but if leases are to be inserted atregular intervals I prefer to add other mechanism, now to be described.I prefer that the leases may be inserted at the same time that acut-mark is applied or attached to the yarn, and I therefore prefer todrive from the pinion 15 the wheel 30, that is supported upon the stud3l. The stud 31 is attached to and supported by the swinging support 32,which is secured and swings upon the 'stud 17 in a similar manner tothat in which the idler-support 10 is secured and supported by the nut13 and collar 12 on the stud 6 by means of the nut 3.7 and the collar38.

To the wheel 30 is secured the pinion 33,

which turns with said wheel 30, and whichy engages with the lease-wheel34. The leasewheel 34 is a change-wheel, and is supported upon a shaft35 by the nut 36 and col- IOC IIO

IIS

lar 39 or other means in such a way that said shaft rotates with saidlease-wheel. The shaft 35 passes through the frame 11 or other suitablesupport, and upon it is also supported the lease cylinder or worm 40.

The lease-cylinder is provided with a notch 41 running longitudinallyupon it, and with another and shorter but deeper notch 42 at its end.The lease-cylinder is provided upon its surface with a worm or screwthread, and in the space between two adjacent screwthreads there worksthe lug 43, which is on the bell-support 44. The lug 43 is made so thatits point may fall into the notches 41 and 42 when it arrives at theproper place to do so; but it is inclined at its back, so that thecylinder 40 will in revolving easily raise the bell-support 44 to itsnormal position, the said inclined part servingto cause the lug 43 orsome part of it to always lie in the groove between two screw-threads.This coustruction of the lug 43 is shown in Fig. 3.

The bellsupport 44 is `supported by the ears 46 upon the shaft22,longitudinally upon which it can be readily moved, and, as thelease-cylinder 40 revolves, the lug 43 drops into the notch 41 at everyrevolution of said cylinder, ringing the bell 45 (which is preferablysupported on a thin flat spring 49) when it falls, thus indicating theproper time for the insertion of the lease and informing the operator ofthe stoppage of the machine. The bell 45 may sometimes be omitted.

I prefer in some cases to cause the falling of the bell-holder 44 (inconsequence of the dropping of the lug 43 into the notch 41) to stop themachine, and this result is readily attained by holding up the weight 23by said bell-holder by means of the dog 47, which is attached to theshaft 22 by a set-screw 87 or other suitable means, and which usuallyrests upon the longitudinal bar 48, that is connected with thebell-holder 44. The dog 47 may be adjusted upon the shaft 22 in such away that the machine may either be stopped at the end of every cut oronly atthe time that a lease is inserted. The latter method ofadjustment is illustrated in Fig. 3. I usually form two iiat places inthe proper positions on the shaft 22 for the end of the set-screw 87 inthe dog 47 to strike, and said set-screw is adjusted to strike one orthe other of these fiat places as the machine is or is not desired tostop at the end of every cut.

The machine may be made to stop at the end of every cut by adjusting thedog 47 to allow the shaft 22 to rock downward far enough to stop themachine before the dog strikes the bar 48, the weight 23 being held upin that case by the end of the arm 20, which then would rest upon theeut-cylinder 18. The pins 27 may be made to engage with any desiredspace in the pinion 15, thus enabling the operator to adjust the device,so that the lug 43 and the end of the arm 2O will simultaneously fallinto the notches made for the purpose.

If the device is to be used simply for the insertion of leases, thespring 29 may beloosened or removed, so that the gong 26 will neverring, while if both cut marks and leases are to be inserted the spring29 is put into place and the operator is informed by the ringing of thebell 45, with the striking of the gong 26,when to put in a lease. Theendof the warp is indicated by the lug 43 dropping into the deep notch 42,and thus more violently than usual ringing the bell 45.

The number of cuts in a lease may be easily fixed by ehoosing alease-wheel 34 with the proper number of teeth, and I find it usuallyconvenient to so arrange the gearing that four teeth on the lease-wheelmay be equal to one cut, although any other convenient number may bechosen instead of four for this purpose. The number of leases in a warpis controlled by not using the whole of theleasecylinder, but by raisingthe lug 43 from between the screw-threads and moving it away from theend containing the notch 42 until it has passed as many threads of thescrew on the surface of the lease-cylinder as there are desired to beleases in the warp. The shaft. 22 may be graduated and numbered, if sodesired, to facilitate this operation.

The gong 26 may be omitted sometimes, and sometimes some other form ofbell may be substituted therefor, if so desired.

The mechanism driven by the pinion 15 may sometimes be omitted, as wellas the pinion 15 itself, if it is desirable todo so, the cutcylinder 18being in that case directly attached to thecut-wheel 14.

I do not desire to limit myself to the exact construction of all theparts as illustrated, nor to using this yarn-measuring device only onwarping-machin es.

Vhen it is only desired to stop the machine for the insertion of theleases in a IOO IIO

warp and it is known that it will not be necworm without thelongitudinal notch 41 and provided with a notch in its end like thenotch 42, combined with a piece much resembling the piece 44, butwithout the bell attached thereto, and used in connection with a devicefor stopping a machine, has been used in connection with ameasuring-roll and a train of gearing connecting said roll and said wormfor the purpose of stopping a war`ping-machine at the end of a warp, andI do not claim such as of my invention; but
